     Sounds good, but I'm still looking for the hole to plug my one
must-have item into.  Limp Home Mode.  For my particular application,
LHM is crucial to the point that I've been dreaming up digital-over-
analog EFI's, at least that's the best term I can give it, but the
concept should be obvious.  Before I wander too far here, has any 
work been done along these lines?
